DATING-STATE? Specification of Letters Patent. Patented Mar. 24, 1914;. Applibat'lon filed August 31, 1912. Serial No. 718,116:

To all whom it may concern;

Be it known that I, HENRY M. G. PINKER- TON, a citizenof the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Im; provements in Dating-Stamps, of which the following is a specification.

This invention relates to dating stamps of the character used so universally in railroad ticket ofiices and the object of the invention is to provide a stamp of this character which will be extremely easy of adjustment, and

one in which the adjusting device will indicate the position of the printing wheels;

The invention therefore consists of the stamp as shown in its preferable embodiment in the accompanying drawings and as hereinafter described and claimed.

In the aforesaid drawings: Figure 1 is a perspective view of a dating stamp turned bottom side up in order that the interior parts may be better seen. Fig. 2 is a longitudinal vertical section. Fig. 3 is a vertical section through the line 3-3 of Fig. 2. Fig. 4 is atop plan view of the novel parts of the stamp. Fig. 5 is a perspective View showing the various parts of the changing mechanism separated and spread apart in order that their construction may be better 7 understood.

Referring now to the details of the drawings by numerals: 1 represents the base of a machine such as is now very generally in use, this machine carrying a. set of printing wheels rotating upon an axis 2, "a fixed die 3' being provided over said printing wheels and through which the wheels project,jan

' inkin ribbon 4 passing from a reel 5 over the fixed die 3 to a reel -6 at the rear of the machine.

All the parts so far described may be of the ordinary construction and therefore no further description thereof is needed.

My invention relates more particularly to the means for rotating or setting the printing wheels 2. As in all stamps of this character, the printing wheels consist of a month wheel 8, day wheels 8 and 8 and year wheels 8 and 8. Various means have been proposed by which these wheels may be adjusted or set. In the form shown'in my drawings, I employ a series of toothed wheels 10, 11, 1'2, 13 and 14, there being one wheel for each of the printing wheels. The aforesaid wheels 10 to 14 inclusive are each provided with teeth 16 which are arranged to enter openings 18 in the printing wheels so that, as the toothed orsetting wheels are rotated ontheir axes, their teeth will enter the openings 18 in the printing wheels and turn said printing wheels on their axes, the spring actuated detents20 holding the printing wheels in their adjusted positions. The adjusting or setting wheels 10 to 14 inclusive are supported within the main frame 1 just to the rear of the printing wheels as illustrated in Figs. 2 and 4 and all (if the Wheels are rovided with projecting keys as 24by w ich they are secured to their rotating means which will now be described.

Projecting into the frame of the machine proper size to enter the opening in the firstsetting wheel 14 and to that end it has two notches 34 into which fit the keys 24 of the setting wheel 14. Furthermore the sleeve 30 is just of the proper length to pass into the frame a su'fficient distance to hold the setting wheel 14 in proper operating position in connection with the month .printing wheel 8. A second sleeve 36 of slightly smaller size is adapted to project through the aforesaid sleeve 30, and its inner end is provided with two recesses to coact with the keys on the interior of the setting wheel 13, the opposite end of the sleeve 36 having a thumbwheel 38 by which the sleeve 36 may be rotated within the sleeve whenever necessary. This sleeve 36 is likewise of just the proper diameter to fit within the setting wheel 13 and is of the proper length to hold said setting wheel in operative relation with the day wheel 8*. Fittin within the sleeve 36 is a spindle 40 having a longitudinal groove 41 therein, and this spindle 40 is of sufiicient length to pass through the sleeve 36 projecting therefromsutficiently to pass out of the frame of the other side of the machine, and projecting through said frame as will be hereinafter described. This spindle 40 is of the proper diameter to fit the opening wlthin the setting wheel 12 and the key 42 of through the frame fromj-the other side of the machine, and fitting over the spindle 10 are two sleeves 50 and 51, the sleeve 50- being large enough to have the sleeve 51 passing through it, each of these sleeves have recesses on their inner ends,the recesses in the sleeve 50 fitting the keys 24: on the setting wheel 10 and the recesses on the sleeve 51 receiving the keys of the set-ting wheel 11. From an inspection of Figs. 3 and 5, it will be seen that the sleeve 51 is long enough to pass into and fit the opening in the setting wheelllwhile the sleeve 50 is only long enough to fit the opening within the setting wheel 10. The sleeve 50 is provided with a thumb-wheel 54 and the sleeve 51 with a thumb-wheel 56 by which said wheels may be rotated. After the parts areallassembled in the positions shown in Fig. 3, a wire washer or retaining device 60 is passed around a groove 61 in the end of the spindle 10 and all the parts are locked in position. a

The thumb-wheel 32 which has been described as being secured to the setting wheel 14:, and which cooperates with the month wheel to set the same, has a series of flat faces on its periphery, and these faces have impressed therein the months of the year corresponding with the months on the month wheel 8, and when the parts are assembled, the month appearingon the top side of the month thumb-wheel 32 will cor-- respond with the month on the printing wheel so that the operator may adjust the setting wheel 32 until the proper month on the flat surface of said thumb-wheel is up he will be able to print the month indicated by the thumb-wheel 32. Likewise, the thumb-wheels at the right of the month thumb-wheel 32 and which have been described as having their sleeve and spindle respectively fixed to the setting wheels 12 and 13 which coiiperate with the day printing wheels 8 and 8*, also have the numbers on their faces corresponding with the numbers on the day printing wheels so that the operator merely has to "adjust the thumb-wheels, without looking at the printing wheels, in order to know when the printing wheels, are properly set. The thumb-wheels 54E and56 on the other. end of the spindle 40 are likewise marked so that they control the year setting wheels 10 and 11 and the numbers impressed upon their peripheries correspond with the numbers on the year wheels sov that the operator can readily adjust the latter.

It is believed the operation of my invention is so simple that no description thereof is necessary.

I am aware that it has been heretofore proposed to, operate the printing wheels of a dating stamp by means of toothed wheels intermeshing with the printing wheels, and

therefore, make no claim to such broadly.

However, I' believe I am the first to combine menses such features with operating sleeve and thumb-wheels in the manner hereinbefore described.

What I claim as new is:

1. In a stamp, the combination with "a frame having vertical sidewalls, a series of printing Wheels, a series of toothed or setting wheels journaled between the side walls of said frame, a spindle or. shaft having a thumb wheel on one end of the shaft passing through both side walls and supporting said toothed wheels, two additional thumb wheels on said spindle exterior to said side walls, having sleeves projecting through the side wall nearest the first mentioned thumb wheel,two additional thumb wheels on said spindle on the side opposite the aforesaid thumb wheels and having sleeves passing through its side wall, said spindle, sleeves and toothed wheels having co-acting keys and grooves, and a securing device on the end of said spindle, whereby the single securing device secures the spindle, the

thumb wheels, the sleeves and toothed wheels in cooperative position, substantially as described.

2. In a stamp, the a combination of a frame, a series of printing wheels journaled within said frame and having printing characters on their peripheries with grooves,

between ,said printing characters, a series of toothed or settin wheels also'journale d within said frame in parallel relation to said printing wheels and having teeth enterk ing the grooves between the printing characters on the printing wheels, a series of thumb wheels for turning said toothed wheels, a spindle or shaft connected to one of said thumb wheels and passing through and supporting all the other thumb wheels, said other wheels having sleeves fitting around each other and the spindle, said spindle and the inner ends of said sleeves having notchesand said toothed wheels having keys fitting into said notches, whereby the parts may be easily assembled, substantially as described. 1 1

3.
